Jetting Help, new to the game?

[rward69]

Hi everyone, Im new to the site and glad that I found it. I just purchased a used but excellent condition 03 KLX 400S. Since getting the bike I have opened the air box with the 3X3 mod and drilled the stock exhaust. (and I mean drilled it completly out all the way to the first perferated plate. Extremly louder and better running than stock. Any way I just got my DynaJet kit inthe mail today that I ordered from TT. I am at about 2000ft elevation and needed some advice on jetting to get it right the first time... Thanks

local shop or TT store.

Sorry to be a bother, but again new to the game and with the Kawasaki this is being a pain with the local cycle shop. My bike is the dual purpose "SR" model and since the kit didnt come with the recomended main and pilot I will have to order them. Do you have the part numbers for these items, the 138 main and the 25 pilot to make sure that Im getting the correct parts. Thanks in advance!
